4) PRIMING

Serious damage will occur if a pump is not properly primed

and runs without water.

WARNING

The pump must be primed before operation. To do this completely fill the

pump housing with clean water through the priming plug before switching it

on.

When full replace the priming plug and start the pump checking there is a

steady flow at the pump outlet. The pump should be primed whenever it has

not been used for a long period of time or when air has made its way into

the system.

5. MAINTENANCE

Never carry out any work on the pump without having first

disconnected from the mains supply.

WARNING

Pumps do not require routine maintenance provided the following

precautions are taken:-

Check that the foot valve is clean and unrestricted at regular intervals.

If the pump is to remain unused for long periods of time it is advisable to

empty it completely, rinse it with clean water and store in a dry place.

If the shaft does not run freely, release it using a screwdriver by inserting it

in the special slot on the rear of the pump shaft. If this is not sufficient to

solve the problem remove the pump body by unscrewing the relevant

mounting bolts and clean it thoroughly to remove any encrustation.
